Business 40 Improvement Project

As Winston-Salem's downtown continues to be a thriving urban hub, the 1.2-mile stretch of Business 40 that runs through downtown is underway for structural improvements and overall beautification. The three-year project, spearheaded by the North Carolina Department of Transportation (NCDOT), is a multi-phased project is slated for completion in 2020. The finished project will offer travelers safer roadways in and out of Winston-Salem's bustling downtown, and add and improve pedestrian walkways through and around downtown.

While construction crews work to complete the expansion of Peters Creek Parkway (learn more about that here), the 1.2-mile section of Business 40 between Peters Creek Parkway and U.S. 52. will close on Sunday, November 17, at 6 a.m. Find up-to-date road closure information, along with easy-to-navigate detour routes here.

Upcoming Closures:

November 17 at 6 a.m. a 1.2-mile section of Business 40 between Peters Creek Parkway and U.S. 52 will temporarily close as part of the Business 40 Improvement Project. Sections between downtown Winston-Salem and the I-40 splits, near Clemmons and the Piedmont Triad Farmers Market will remain open. Detour signs will guide pass-through traffic onto I-40. The following downtown road bridges will also close at the same time: Liberty Street, Main Street, and Church Street, as well as the Strollway pedestrian bridge. All of them will be replaced with new bridges.

The project provides wider lanes, longer access and exit ramps, higher bridges, an increased speed limit, a modern look and a new name - Salem Parkway/U.S. 421.

There will be two pedestrian bridges and a tunnel. The footbridges connect the city's Greenway project, providing a walkable route from the Long Branch Trail at the Innovation Quarter in downtown to BB&T Ballpark.

For up to date detours, NCDOT has partnered with Waze to bring you real-time traffic information in and around the Business 40 project site.
